GRAIN-BINDER.

SPEGIFICATICN forming part of' Letters Patent No. 276,519, dated April 24, 1883. Application filed March 29, 1883. tModcl.)

- ing part of this application.

My invention relates to certain new and useful improvements most applicable to that type of grain-hinding machines in which there is a sort of gavel receptacle adapted to receive the cut grain discharged from the upper end of the elevator of a harvester, and in which the grain which is received into said gavel-receptacle is automatically packed into gavel form,is bound into sheaves by a binder mechanism proper,which operates periodically, and is discharged, when bound,from the lower end of said receptacle, although some of the features of my said invention may be used with more or less advantage in grain-binding machinery of a different type.

My invention has for its main objects to render more efficient and certain all the operations of the mechanisms employed for effecting the proper encirclement of the gavel with the cord and the proper tyingup ot' the gavel within the band of cord, (to form a sheaf,) and to render the binding machinery capable of tying up .the grain tighter without any greater or unusual strain on either the cord or the I binding mechanism; and to these main ends and objects my invention consistsin the novel features of construction and operation of varipracticed it in a working-machine, and which manner of carrying out my invention is the best now knownto me, though practice and experience may indicate, either to me or to others, some better way of carrying the same into practical operation.

In the said drawings, Figure 1 is a side elevation of so much as seems necessary to be shown of a grain-binder embracing theseveral features of my said invention. Fig. 2 is a sort of top view of the same, looking at the mechanism vat right angles to .the inclined plate K, in the direction indicated by the arrow .2 at Fig. 1. a: m of Figs. 1. and 2, with the parts viewed in the direction indicated by the arrows z in said figures. Fig. 4 is a similar sectional view, but showing the knotter raised up and to its highest position. Fig. 5 is another similar view, but with the knotter depressed to its lowermost position. Fig. 6 is an. elevation, showing the opposite side to that exhibited at Fig. l, and showing only the cam and rack wheel, the pinion which engages therewith, and the sheaf-discharging arms. Fig. 7 is a partial vertical section at the line 3 y of Fig. 2. Fig. 8 is a similar view, but with the vibratory knotter-frame and its attachments in a different position, and with the position of the cam that lifts said frame changed. Fig. 9 is a detail face view of the cam and rack wheel detached. Fig. 10 is a detail View to illustrate in top view the cord holder or clamp, (the parts being in the relative position they occupy when the cord is clamped by the holder.) Fig. 11 is a detail sectional view at the line y 3 of Fig. 10, but showing the slide of the cord-holder drawn back as it would be at the time of the releasement of the cord.

In the several figures the same part, wherever illustrated, will be found designated by the same reference-letter.

Ais the driving-shaft, from which are derived the motions of all the parts of the binder except those of the needle-arm, the packers, and

Fig.3 is a section at the line' the compressor which acts in opposition to y the needle-arm, (if there be one.) Saidshaftis mounted in the frame of the binder in about the usual manner seen in what is known in the market as an Applebybinder, and it the knotter.

carries the cam and rack wheel B, also a camwheel, 0, which operates the upper cord-pusher, the lower pusher, the cord-knife, and the slide of the cord-holder, (all as will be presently more fully explained,)and alsoa cam,D, which operates to lift the knotter-frame E, in a manner to be presently explained.

The knotter-frameE is hung atits bifurcated end on a counter-shaft, F, on which it swings axially of said shaft to a given extent, for the purpose of the elevation and depression (as occasion may require) of the knotter G, the lifting of the knotter and of said frame being affected by the cam D, and the extent to which said frame can be thrown up being restricted by a stop, H.

The shaft F is mounted to turn freely in the bearing-boxes at a a in the casting or metallic stand I) of the binder, and, while it serves as the pintle about which the frame E vibrates, it acts also to drive through the medium of beveled gears c and at the shaftor spindle e of Motion is imparted to the shaft F for the purpose just mentioned by a spurpinion, I, which periodically engages with and is once rotated by the teeth J of the cam and rack wheel. This spur-pinion I is formed or provided with three lateral projections or luglike devices,f, g, and 71-, the first and third of which, actingtogether, serve to hold the pinion from turning while the wheel B is making a certain part of its revolution, while the one lettered g is for the purpose of turning the shaft 6 back a quarter-turn by the action of a cam-like projection, 7 of wheel B, and the one lettered It acts by itself as a stop to the return movement of said knotter-shalt c, all as will be hereinafter more fully explained.

K is the metallic plate, located above and forming, so to speak,the usual top or roof-like portion of the gavel-receptacle. This plate K is slotted or cut out at j for the passage through it of the forward portion or end of the needIearm, and has the slotted part j formed so that the cord will be properly guided as the needle-arm laysitover the knotter, and so that the upper fold or portion of the cord for the sheaf-band will lie immediately beneath the horizontal shoulder portion j of said cut-out portion.

L is the upper and M thc lower cord-pusher, while N is the cord-knife. All three of these devices are formed on or secured to carriage O, which slides in suitable guideways, 7c 70, on the plate K, and which is moved back and forth by one end of a lever, I, which at its opposite end is pivoted to an arm, Z, of the frame I), the said lever P being vibrated at the proper time and to the requisite extent by the action of cam-wheel c on an anti-friction roller pivoted to lever P at the point m.

On the cam-wheel (J is a cam-like lug portion, a, which strikes at the proper time against the roller 0 for the purpose of forcing back (to open the cord-holder) the sliding bar Q. This bar Q is moved and held in the opposite direction (to keep the cord-holder closed) by a strong spiral spring, q, and its operative end is made rounding, as shown, so as to coaet, in a manner to be presently explained, with a stationary recessed piece, R, for the purpose of holding fast on or clamping the cord. This piece It is formed with a small horn, r, for a purpose which will hereinafter appear.

The knotter is very analogous to the kind used in the well-known Appleby binder, and is composed of a bill-likedevice, 8, having combined with it a swinging jaw-piece, t, the heel u of which is acted on by a strong spring-plate, 1 A little way below the bill of the knotter is a cord-rest, 'w, the operation of which will be presently explained.

In the operation of my improved machine the parts shown in the drawings work separately and together, as I will now explain.-

Supposing the knotter to be elevated to that position where it must be when the roller m of the swinging frame E is resting on the circular part of the periphery of cam D, and supposing, also, the banding-cord is held fast between the slide Q, and stationary jaw R ofthe cord-holder, the gavel is formed in the loop of the cord, about as usual, andwhen the binder devices proper start into operation the needlearm carries the second fold of the cord over and aroundthe gavel (about as usual) andlays itover the bill and jaw of the knotter, (these two parts being closed together at this time and the knotterin a horizontal position,) carrying said fold of the cord down below and placing it alongside of the slide Q of the cord holder. The shape of the slot in plate K is such as to insure the guidance of this second fold of the cord, so that it will be properly laid over the knotter, along with the first fold, (that comes from the cord-holder upward, thence over the knotter, and thence downward under the gavel.) The second fold of the cord is guided to a position such that after leaving the knotter it passes obliquely upward and beneath the ledge atj of plate K. The next operations now are by the knotter and the carriage O, the former of which is lifted to its highest position, while at the same time the upper and lower pushers, L and M, of said carriage'operate, the former to push the upper part of the second fold of the cord well along beneath the ledge j and thelatter to push the lower part of said fold of the cord along to a position near the end of slide Q, and between it and the horn r. Bythese operations the holding down of the upper fold of the cord at a short distance from the knotter is insured, and the direction in which this fold of thecord runs off from the top of the knotter is so changed (by the elevation of the knotter bodily) that when the knotter shall subsequently turn there will be no possibility of the cord being missed by the bill and jaws as they turn the cord over and around themselves. The

knotter, when thus raised to its highest position, is carried up toa point such that in de scending therefrom to its lowermost position it will have an opportunity to take up or wind up onto itself all the cord necessary to be takenup of the two folds running from the knotter down toward the cord-holder. Of coursewhen the knotter ascends, as first explained, to the highest position its bill and jaw slide against both folds of the cord that lie over the knotter, (one of which folds is-held down to the cord-holder over the other by the needle-eye,) and when the knotter descends it rotates at the same time on the axis of shaft 0, to do the tying up of the knot.

The descent of the knotter is caused by the pull thereon, or, in other words, by the winding up on the knotter of the two folds of the cord, together with thegravity of the knotter-frame, 850.; but this descent is regulated and timed by the shape of a. portion of the periphery of cam I). Inasmuch as the descent of the knotter and the tying up of the cord occur while the necdle-arm is about finishing its forward stroke, it follows that the final compression of the gavel between the needle-arm and the opposing compressor will occur justat the righ't'time to prevent any undue strain on the cord while being tied up close around the bundle by the action of the knotter, and this timing, so to speak, of the operations of the compressing and tying devices is important. In forming the knot during the descent of the knotter, as

just explained, thebill portion or head 8 and the jaw t operate together about in the manner these parts work in the knotter of what is well known in the market as the Appleby binder; but to avoid any slipping ofl of the lower fold of the cord during that part of the knotters revolution where the bill and jaw are in nearly or quite a vertical position, a retaining device, 10, is added, which acts to hold up and on the knotter the lower fold oftho cord. This retainer to, extending, as it does, from the piece carrying the spring 3 is temporarily locked fast to the bill and jaw of the knotter at the time the latter completes the tying oporation, so that during a quarter-turn backward of the knotter (to permit the drawing off of the knot) this retaining device is obliged to turn down into avertical position, and hence does not at such time interfere with the pullin g off of the knotted cord. A

The retaining device w is made quite thin, and is placed close up to the head of the-knotter, and as no stripping device is required it will be seen that the head of the knotter can work close up to the plate-K, and consequently close. up to the bundle of grain. The great advantage, of course, of this is that the knot can betied so close to the grain that no slack in the band will be left for the grain of the sheaf to expand into. The capacity of the knotter to permit the pulling off of theknot and to work close up to the grain arises from the following novel mode of operation, vizz After having completed its revolution about the axis of shaft 6, (effected by the engagement-of the teeth J of the cam and rack wheel with the pin I,) the knotter is turned backward] y a quar-\ ter-revolution, so as to have its bill point downward, (the retainer n; being turned with it.) In this position, it will be observed, the tied knot can easily be pulled off ofthe bill by the discharge of the sheaf, which is swept out by the sheave-discharging arms U U; but toexpedite and-insure the extrication of the knot from the K, The backward movementof the knotter is positively assured by the action of a lug or tappet, t, of the rack-wheel B coming against the projectionh of pinion I, and causing a quarter turn of the latter, though in some cases, with the knotter made a little difi'erently, this back movement of the latter might be affected wholly by the pull of the outgoing sheaf. Of course the first fold of the cord will have been released and the second fold of the cord (held in the cord-holder) will have been cutduring thefore part of the ascending movement of the knotter. As the cordholder lets go of the first fold of thc cord the latter is pulled up out of the way, and in reclosing the cord-holder clamps only the second f eld, (above the needle-eye,) which second fold, having been pushed to the right place by pusher M, naturally draws into the bite of the cord holder. At this time the knife N is forced hard against the second fold of the cord, and then as the knotter ascends the action of the knife during its further movement is facilitated by the rise of the knotter. The backward quarter-turn of the knotter occurs, it will be understood, immediately after the releasement of the first fold, the clamping of the second, and the cutting of the latter, (which three operations occur in rapid succession.) As the knotter in rising to assist the extrication of the knot, goes on and up to its highest elevation, it follows that the escape of the boundbundle is facilitated by the knotter pull ing the tied ends of the cord away from the bottom of the slot in plate K. The knotter now partially descends to its first-mentioned position, the shoulder at I) of the wheel B coming against the lug gof pinion and turning the shaft 6 so as to place the hill (and 'closedjaw) of the knotter in a horizontal position, ready to tie another bundle.

It willhe seen that the cord-holder is formed arcs come against the cord.

neath and upwardly around the outside of and against the horn or prong r, and every time the needle descends to encircle the gavel with cord it lays the next fold of the cord alongside of the slide Qand clear of the prong r, so

that when the pusher M shall move forward it will push the latter fold up near to the point where the slide Q and piece 1% come together, from whence said cord fold will naturally be -drawn into the bite of the cord-holder when the latter opens to let out the fold already held in it. The functions of the horn r are these: First, it helps to hold fast the clamped cord, since. the latter takes a partial turn around it as it passes from the cord-holder beneath and up past the side of said horn; second, it pre-j vents any entanglement of the outgoing and incoming folds of the cord, since one fold passes down from the cord-holder and thence up outside of the horn, while the other fold is pushed in a vertical condition past the lower crooked end of the first-named fold; and, third, it insures the clearing of the'released first fold of the cord from the cord -ho lder when the latter is closing on the second fold, because at this time, thetirst fold being pulled upward, the lower crooked end is forced by the horn to come away from the cord-holder, instead of possibly dangling in a pendent position over the cord-holder, where its lower end might be caught in the closing of the slide Q to grip the new fold.

The construction and timing of the cams and other parts are such, it will be seen, that the cord-holder quickly releases the clamped fold of the cord just about as the knotter has completed its tying revolution, and then, after the knotter has moved up some, to pull out the end of the cord released by the cord-holder, the latter closed by the action of its spiral spring and clamps the second or outer fold of the cord. Then, during a slight rest of the k hotter in one position, the knife comes up and pushes against this second fold, so that when the knotter resumes its ascending movement it will assist the knife in its work.

In order to more easily move the slide Q in opposition to the spring q, and with the quick motion requisite, I use the cam-like device a, acting on the anti-friction roller 0, and mount the latter and the rear end of slide Q on a pivot, a arranged at the'upper end of a link, c (hung by a pivot, 6", to the stand f and and the parts are made to work smoothly and durably. v
